^ Barkley basically averaged a double double every season of his career. 15 straight seasonsof grabbing 10 rebounds per game. his career in a nutshell is being one of the best reboundings player's ever....all while standing barely 6'5. Let alone being a dominant force on offense.

His work ethic did hold his longevity down but his peak is among the all time greats.

And even while not having the best practice/training/eating habits, he did have a lot of longevity.

Putting up 16 and 12 at age 36, while having all those back problems and other wear-and-tear.
